The Wendy’s Company WEN is slated to release first-quarter 2018 results on May 8, after the closing bell.The company’s top line is expected to be benefited from continued sales boosting efforts and system optimization initiatives are likely to give a boost to the bottom line in the quarter to be reported.In a year’s time, the company’s shares have rallied 11.1%, outperforming the industry’s 3.2% gain.Given this backdrop, let’s delve deeper to find out the factors likely to have a bearing on the company’s first-quarter results.Sales Boosting Efforts to Pay OffIn the recent quarters, Wendy’s has witnessed a year-over-year decline in revenues. Even in the fourth quarter of 2017, the company’s top line marginally declined year over year, driven by lower sales at its company-operated restaurants, partially offset by higher franchise royalty revenues, fees and rental income.However, we expect reversal of this trend in the to-be-reported quarter. The Zacks Consensus Estimate for revenues is pegged at $380 million, reflecting a 32.9% increase compared with the year-ago quarter’s actual figure. Increased investments in technology like mobile payment and ordering, and customer self-order kiosks as well as efforts like re-imaging of restaurants and new menu offering are anticipated to drive traffic, and in turn sales.Same-Store Sales to GrowNotably, fourth-quarter 2017 marked the 20th consecutive quarter of same-store sales growth for Wendy’s. This indicates long-term strength and relevance of the brand. We expect the company to maintain the trend in the soon-to-be-reported quarter through its solid menu pipeline, limited time offers (LTO), marketing initiatives, and increased emphasis on core and price value offerings. In fact, for the first quarter of 2018, the consensus estimate for system-wide comps calls for growth of 1.8%, comparing favorably with 1.3% growth in the last-reported quarter.System Optimization Initiatives to Boost EarningsAlthough increased costs related to other sales-boosting initiatives and higher wages might weigh on margins, the system optimization initiatives are likely to boost the quarter’s earnings on reduced expenses. For the first quarter, the consensus estimate for earnings stands at 10 cents, reflecting 11.1% growth year over year.Also, in the last reported quarter, system optimization favored the company’s adjusted EBITDA, which grew 14.2% from the year-ago level.Our Model Doesn’t Suggest a BeatAccording to the Zacks model, a company with a Zacks Rank #1 (Strong Buy), 2 (Buy) or 3 (Hold) has a good chance of beating estimates if it also has a positive Earnings ESP.
